Magnetic component cooling structure and power converter having the same

Abstract

Provided is a cool air flow space in which cool air, that is generated by an inner fan disposed inside a housing, flows in the housing. An attachment member mounts a magnetic component on a bottom portion of the housing at a position within the cool air flow space. The attachment member includes a top plate and a pair of legs that extends downward from the top plate and that is fixed to the bottom portion.
